The document discusses how traditional thinking vs agile thinking approaches different scenarios in software development. It presents scenarios related to retesting, utilization, scope-driven development, meetings, and planning. For each scenario, it contrasts the assumptions and benefits of the traditional vs agile approaches. The key aspects of agile thinking emphasized are continuous delivery, rapid feedback, responding to change, incremental development, optimizing the whole workflow, and valuing individuals, interactions, and collaboration over processes and tools.

Challenging traditional thinking with Agile

- 4. Scenario: Retesting "Well, there's no point in testing now, If the code changes, I'll just need to re-test all this stuff anyway. Call me when things stop changing."
- 5. Traditional thinking Scenario: Retesting • What's the assumption taken? – Things will stop changing – Testing time = tests execution time – Testing role certifying the product is ready for delivery • The benefits – Test execution time potentially will be reduced – People motivation – Test coverage is easier to track
- 6. Agile thinking Scenario: Retesting • The assumption – Things will keep changing – The role of the tester is Improving the quality of the product before it's complete • Benefits – Total delivery time potentially reduced – Fixes are simpler (risktime) – Tester role is more relied on and critical – leading role – Progress is more reliable – Increase in quality
- 7. Agile thinking Scenario: Retesting • Potential challenges: – More testing time – Doing the same again and again – low motivation – Effort on automation
- 8. Agile Thinking concepts Scenario: Retesting Optimize the whole flow Stop starting start finishing Lean Agile Early feedback Scrum Kanban Incremental development, Work as one Team, Build Quality In – Automation, Continuous XP integration, Unit tests
- 9. Scenario: Utilization “Should I start something new that is waiting for me ?”
- 10. Traditional thinking Scenario: Utilization • The assumption taken – I’m measured as efficient by the pace I produce • The benefits: – People’s skills are highly utilized
- 11. Agile thinking Scenario: Utilization • The assumption – Effectiveness is measured by the time it takes us to get things done – from concept to consumption – Optimize the whole vs. Local optimization – Work as one team Can I help directly? Do something in my domain that doesn’t create work down stream ?Or assist in making downstream faster ? Innovation ? Improvement backlog?
- 12. Scenario: Scope Driven "We must include this new capability in this release, it’s strategic. It will result with postponing in 2 -3 months the release date"
- 13. Traditional thinking Scenario: Scope Driven • What's the assumption taken? – Customer knows what they want • Potential problems: – You may loose the window of opportunity – Time expands - Student syndrome, Parkinson’s law – Your team will run out of energy – You end up with “scope creep”
- 14. Agile thinking Scenario: Scope Driven • The assumption – Early feedback – Continuous short delivery cycles – Customers discover what they want • Benefits : – Incremental value & ROI – build customer trust – Easy to plan – Creates sense of urgency – 80/20 rule (less is more)
- 15. Agile thinking Scenario: Scope Driven • Potential challenges: – Short term view – High investment in reduce cost of release – Late adapters “Timebox — don't scopebox” — Mary Poppendieck , Leading lean software development
- 16. Agile Thinking concepts Scenario: Scope driven Optimize the whole flow Stop starting start finishing Lean Deliver fast Agile Customer collaboration Early feedback Responding to change Scrum Kanban Project management framework: Incremental Engineering Practices: Build development, XP Work as one Team, Quality In – Automation, Continuous integration, Unit Sprints - timeboxing, tests Product Owner
- 17. Scenario: Meetings “All day we are in endless meetings, there is no time to do real work”
- 18. Traditional thinking Scenario: Meetings • The assumption taken? – Work is what we do out of the meetings (code, test…) – Machine model: Each part can be built separately and be assembled at the end • Potential problems: – More documentation – More Process
- 19. Agile thinking Scenario: Meetings • The assumption – Team face-to-face communication is most effective – Engineers discover how to build the product • Benefits : – Focus – Tight feedback – Ownership – Team spirit – Transparency
- 20. Practices that can help Scenario: Meetings • Collaborative games – Fun • Physical participation • Visualization • Repeated Structure • Small • Facilitator • Own a meeting • Publish Agenda, goal, outcome • Time-boxing • Close the meeting explicitly
- 21. Agile Thinking concepts Scenario: Meetings Optimize the whole flow top starting start finishing eliver fast Lean Individuals & Interactions Customer collaboration Agile Early feedback Responding to change Scrum Kanban Incremental development, Work as one Team, Sprints - time Build Quality In – Automation, boxing, Product XP Owner, Cross Continuous integration, Unit tests, functional teams, ceremonies
- 22. Scenario: Planning “We are bad at estimating, we never live up to our plans”
- 23. Traditional thinking Scenario: Planning • The assumption taken – Engineers knows in advanced how to build the product
- 24. Agile thinking Scenario: Planning • The assumption – Engineers discover how to build the product – It’s an emerging process – complex system – Empirical data = Velocity, Working software – Continuous planning = adapt the plan according to the team's capability
- 25. Agile Thinking concepts Scenario: Scope driven Optimize the whole flow Stop starting start finishing Deliver fast Lean Working software Individuals & Interactions Customer collaboration Agile Early feedback Responding to change Scrum Kanban Incremental development, Work as one Team, Sprints - time Build Quality In – Automation, boxing, Product XP Owner, Cross Continuous integration, Unit tests, functional teams, ceremonies, PSP
- 26. Adaptability Agile is a method to deliver value to the customers, not a dogma

- Practice 80/20 rule. 80/20 rule refers to the phenomenon where 20% of causes lead to 80% of the results. Quit trying to be a perfectionist and focus on the 20% of the things that matter. Read my 3-part series on 80/20 Principlefor more on 80/20 rule and how to implement it in your life.Time box. Set aside a fixed time slot to work on your tasks. You must work on that task and only that task during that time slot, no more, no less. (Hence the term, time ‘box’, since the task is boxed within the time). Most people set aside a time to work on a task and continue working on it till they are done, even if it means exceeding the time. Because of that, they develop the mentality that it’s okay not to finish a task within the allotted time slot since there’s time later to do it. This decreases their productivity. With time boxing, the non-negotiable cut-off timing makes you more productive.Picture:http://personalexcellence.co/blog/boost-your-productivity-in-50-ways/
